This is moot for another reason.
Your eyes take in the full spectrum of color and produce 3 scalar values for red, green, and blue.
One can take a work of art, illuminate it with pure white light (containing all colors, not just red, green, and blue), determine these RGB values that your eyes will experience, and store them in an image file. You can takes this file and reproduce the work on a computer monitor, on a printer, etc. It will look the same as the work of art under white light.
As soon as you illuminate the work of art with different light, all bets are off. The RGB values do not contain enough information to determine what the work of art would look like under arbitrary spectrum.
For extreme examples consider the following effects:

Conclusion: illuminating a reproduction under different light, or processing a reproduction (an image file) in a computer, will not necessarily give you an accurate representation of what the original would look like. We need more information to know if what they saw in that light room is actually what the original would look like under that light. The same goes for the examples on the page.
